Auto-de-blu($15) can be described as a dark, matte blue that works well with most eye colors. I like to use it along my lower lash line. I won't say MAC Technakohl liners are the softest when it comes to lining my upper lash line. But, they work really well on my lower lash line and adhere well to my waterline too.
I do however like the staying power of these liners. Auto-de-blu stays on for about 4-5 hours and does not smudge all over the place. It works well as a base for certain eye shadows too. It takes a while to set which is great if you want to smudge it out.
